BACKGROUND

All publications cited in this application are herein incorporated byreference.

There are numerous steps in the development of any novel, desirableplant germplasm. Plant breeding begins with the analysis and definitionof problems and weaknesses of the current germplasm, the establishmentof program goals, and the definition of specific breeding objectives.The next step is selection of germplasm that possesses the traits tomeet the program goals. The goal is to combine in a single variety animproved combination of desirable traits from the parental germplasm.These important traits may include higher seed yield, resistance todiseases and insects, better stems and roots, tolerance to drought andheat, and better agronomic quality.

Soybean, Glycine max (L.) Merr., is an important and valuable fieldcrop. Thus, a continuing goal of soybean plant breeders is to developstable, high yielding soybean cultivars that are agronomically sound.The reasons for this goal are to maximize the amount of grain producedon the land used and to supply food for both animals and humans. Toaccomplish this goal, the soybean breeder must select and developsoybean plants that have traits that result in superior cultivars.

The foregoing examples of the related art and limitations relatedtherewith are intended to be illustrative and not exclusive. Otherlimitations of the related art will become apparent to those of skill inthe art upon a reading of the specification.

The complexity of inheritance influences choice of the breeding method.Backcross breeding is used to transfer one or a few favorable genes fora highly heritable trait into a desirable cultivar. This approach hasbeen used extensively for breeding disease-resistant cultivars. Variousrecurrent selection techniques are used to improve quantitativelyinherited traits controlled by numerous genes. The use of recurrentselection in self-pollinating crops depends on the ease of pollination,the frequency of successful hybrids from each pollination, and thenumber of hybrid offspring from each successful cross.

Promising advanced breeding lines are thoroughly tested and compared toappropriate standards in environments representative of the commercialtarget area(s) for three or more years. The best lines are candidatesfor new commercial cultivars; those still deficient in a few traits maybe used as parents to produce new populations for further selection.

These processes, which lead to the final step of marketing anddistribution, usually take from eight to twelve years from the time thefirst cross is made. Therefore, development of new cultivars is atime-consuming process that requires precise forward planning, efficientuse of resources, and a minimum of changes in direction.

A most difficult task is the identification of individuals that aregenetically superior, because for most traits the true genotypic valueis masked by other confounding plant traits or environmental factors.One method of identifying a superior plant is to observe its performancerelative to other experimental plants and to a widely grown standardcultivar. If a single observation is inconclusive, replicatedobservations provide a better estimate of its genetic worth.

The goal of soybean plant breeding is to develop new and superiorsoybean cultivars and hybrids. The breeder initially selects and crossestwo or more parental lines, followed by repeated selfing and selection,producing many new genetic combinations. The breeder can theoreticallygenerate billions of different genetic combinations via crossing,selection, selfing and mutations. Therefore, a breeder will neverdevelop the same line, or even very similar lines, having the samesoybean traits from the exact same parents.

Each year, the plant breeder selects the germplasm to advance to thenext generation. This germplasm is grown under different geographical,climatic and soil conditions and further selections are then made duringand at the end of the growing season. The cultivars that are developedare unpredictable because the breeder's selection occurs in environmentswith no control at the DNA level, and with millions of differentpossible genetic combinations being generated. A breeder of ordinaryskill in the art cannot predict the final resulting lines he develops,except possibly in a very gross and general fashion. The same breedercannot produce the same cultivar twice by using the same originalparents and the same selection techniques. This unpredictability resultsin the expenditure of large amounts of research monies to developsuperior new soybean cultivars.

The development of new soybean cultivars requires the development andselection of soybean varieties, the crossing of these varieties andselection of superior hybrid crosses. The hybrid seed is produced bymanual crosses between selected male-fertile parents or by using malesterility systems. These hybrids are selected for certain single genetraits such as pod color, flower color, pubescence color or herbicideresistance which indicate that the seed is truly a hybrid. Additionaldata on parental lines, as well as the phenotype of the hybrid,influence the breeder's decision whether to continue with the specifichybrid cross.

Breeding programs combine desirable traits from two or more cultivars orvarious broad-based sources into breeding pools from which cultivars aredeveloped by selfing and selection of desired phenotypes. Pedigreebreeding is used commonly for the improvement of self-pollinating crops.Two parents that possess favorable, complementary traits are crossed toproduce an F₁. An F₂ population is produced by selfing one or severalF₁s. Selection of the best individuals may begin in the F₂ population;then, beginning in the F₃, the best individuals in the best families areselected. Replicated testing of families can begin in the F₄ generationto improve the effectiveness of selection for traits with lowheritability. At an advanced stage of inbreeding (i.e., F₆ and F₇), thebest lines or mixtures of phenotypically similar lines are tested forpotential release as new cultivars.

Using Soybean Cultivar 179565921658 to Develop Other Soybean Varieties

Soybean varieties such as soybean cultivar 179565921658 are typicallydeveloped for use in seed and grain production. However, soybeanvarieties such as soybean cultivar 179565921658 also provide a source ofbreeding material that may be used to develop new soybean varieties.Plant breeding techniques known in the art and used in a soybean plantbreeding program include, but are not limited to, recurrent selection,mass selection, bulk selection, mass selection, backcrossing, pedigreebreeding, open pollination breeding, restriction fragment lengthpolymorphism enhanced selection, genetic marker enhanced selection,making double haploids, and transformation. Often combinations of thesetechniques are used. The development of soybean varieties in a plantbreeding program requires, in general, the development and evaluation ofhomozygous varieties. There are many analytical methods available toevaluate a new variety. The oldest and most traditional method ofanalysis is the observation of phenotypic traits, but genotypic analysismay also be used.

Additional Breeding Methods

One embodiment is directed to methods for producing a soybean plant bycrossing a first parent soybean plant with a second parent soybeanplant, wherein the first or second soybean plant is the soybean plantfrom soybean cultivar 179565921658. Further, both first and secondparent soybean plants may be from soybean cultivar 179565921658.Therefore, any methods using soybean cultivar 179565921658 are part ofthe embodiments: selfing, backcrosses, hybrid breeding, and crosses topopulations. Any plants produced using soybean cultivar 179565921658 asat least one parent are also within the scope of the embodiments. Anysuch methods using soybean variety 179565921658 are part of theembodiments: selfing, sibbing, backcrosses, mass selection, pedigreebreeding, bulk selection, hybrid production, crosses to populations, andthe like. These methods are well known in the art and some of the morecommonly used breeding methods are described herein. Descriptions ofbreeding methods can be found in one of several reference books (e.g.,Allard, Principles of Plant Breeding (1960); Simmonds, Principles ofCrop Improvement (1979); Sneep, et al. (1979); Fehr, “Breeding Methodsfor Cultivar Development,” Chapter 7, Soybean Improvement, Productionand Uses, 2^(nd) ed., Wilcox editor (1987)).

The following describes breeding methods that may be used with soybeancultivar 179565921658 in the development of further soybean plants. Onesuch embodiment is a method for developing a cultivar 179565921658progeny soybean plant in a soybean plant breeding program comprising:obtaining the soybean plant, or a part thereof, of cultivar179565921658, utilizing said plant, or plant part, as a source ofbreeding material, and selecting a soybean cultivar 179565921658 progenyplant with molecular markers in common with cultivar 179565921658 and/orwith morphological and/or physiological characteristics selected fromthe characteristics listed in Tables 1 and/or 2 and/or 3 and/or 4.Breeding steps that may be used in the soybean plant breeding programinclude pedigree breeding, backcrossing, mutation breeding, andrecurrent selection. In conjunction with these steps, techniques such asRFLP-enhanced selection, genetic marker enhanced selection (for example,SSR markers), and the making of double haploids may be utilized.

Another method involves producing a population of soybean cultivar179565921658 progeny soybean plants, comprising crossing cultivar179565921658 with another soybean plant, thereby producing a populationof soybean plants which, on average, derive 50% of their alleles fromsoybean cultivar 179565921658. A plant of this population may beselected and repeatedly selfed or sibbed with a soybean cultivarresulting from these successive filial generations. One embodiment isthe soybean cultivar produced by this method and that has obtained atleast 50% of its alleles from soybean cultivar 179565921658.

One of ordinary skill in the art of plant breeding would know how toevaluate the traits of two plant varieties to determine if there is nosignificant difference between the two traits expressed by thosevarieties. For example, see, Fehr and Walt, Principles of CultivarDevelopment, pp. 261-286 (1987). Thus, embodiments include soybeancultivar 179565921658 progeny soybean plants comprising a combination ofat least two cultivar 179565921658 traits selected from the groupconsisting of those listed in Tables 1 and/or 2 and/or 3 and/or 4 orsoybean cultivar 179565921658 combination of traits listed in theSummary, so that said progeny soybean plant is not significantlydifferent for said traits than soybean cultivar 179565921658 asdetermined at the 5% significance level when grown in the sameenvironmental conditions. Using techniques described herein, molecularmarkers may be used to identify said progeny plant as a soybean cultivar179565921658 progeny plant. Mean trait values may be used to determinewhether trait differences are significant, and preferably the traits aremeasured on plants grown under the same environmental conditions. Oncesuch a variety is developed, its value is substantial since it isimportant to advance the germplasm base as a whole in order to maintainor improve traits such as yield, disease resistance, pest resistance,and plant performance in extreme environmental conditions.

Progeny of soybean cultivar 179565921658 may also be characterizedthrough their filial relationship with soybean cultivar 179565921658, asfor example, being within a certain number of breeding crosses ofsoybean cultivar 179565921658. A breeding cross is a cross made tointroduce new genetics into the progeny, and is distinguished from across, such as a self or a sib cross, made to select among existinggenetic alleles. The lower the number of breeding crosses in thepedigree, the closer the relationship between soybean cultivar179565921658 and its progeny. For example, progeny produced by themethods described herein may be within 1, 2, 3, 4, or 5 breeding crossesof soybean cultivar 179565921658.

As used herein, the term “plant” includes plant cells, plantprotoplasts, plant cell tissue cultures from which soybean plants can beregenerated, plant calli, plant clumps, and plant cells that are intactin plants or parts of plants, such as embryos, pollen, ovules, flowers,pods, leaves, roots, root tips, anthers, cotyledons, hypocotyls,meristematic cells, stems, pistils, petiole, and the like.

Pedigree Breeding

Pedigree breeding starts with the crossing of two genotypes, such assoybean cultivar 179565921658 and another soybean variety having one ormore desirable characteristics that is lacking or which complementssoybean cultivar 179565921658. If the two original parents do notprovide all the desired characteristics, other sources can be includedin the breeding population. In the pedigree method, superior plants areselfed and selected in successive filial generations. In the succeedingfilial generations, the heterozygous condition gives way to homogeneousvarieties as a result of self-pollination and selection. Typically inthe pedigree method of breeding, five or more successive filialgenerations of selfing and selection is practiced: F₁ to F₂; F₂ to F₃;F₃ to F₄; F₄ to F₅; etc. After a sufficient amount of inbreeding,successive filial generations will serve to increase seed of thedeveloped variety. Preferably, the developed variety compriseshomozygous alleles at about 95% or more of its loci.

Backcross Breeding

Backcross breeding has been used to transfer genes for a simplyinherited, highly heritable trait into a desirable homozygous cultivaror inbred line which is the recurrent parent. The source of the trait tobe transferred is called the donor parent. After the initial cross,individuals possessing the phenotype of the donor parent are selectedand repeatedly crossed (backcrossed) to the recurrent parent. Theresulting plant is expected to have the attributes of the recurrentparent (e.g., cultivar) and the desirable trait transferred from thedonor parent.

In addition to being used to create a backcross conversion, backcrossingcan also be used in combination with pedigree breeding. As discussedpreviously, backcrossing can be used to transfer one or morespecifically desirable traits from one variety, the donor parent, to adeveloped variety called the recurrent parent, which has overall goodagronomic characteristics yet lacks that desirable trait or traits.However, the same procedure can be used to move the progeny toward thegenotype of the recurrent parent, but at the same time retain manycomponents of the nonrecurrent parent by stopping the backcrossing at anearly stage and proceeding with selfing and selection. For example, asoybean variety may be crossed with another variety to produce a firstgeneration progeny plant. The first generation progeny plant may then bebackcrossed to one of its parent varieties to create a BC₁ or BC₂.Progeny are selfed and selected so that the newly developed variety hasmany of the attributes of the recurrent parent and yet several of thedesired attributes of the nonrecurrent parent. This approach leveragesthe value and strengths of the recurrent parent for use in new soybeanvarieties.

Therefore, an embodiment is a method of making a backcross conversion ofsoybean variety 179565921658, comprising the steps of crossing a plantof soybean variety 179565921658 with a donor plant comprising a desiredtrait, selecting an F₁ progeny plant comprising the desired trait, andbackcrossing the selected F₁ progeny plant to a plant of soybean variety179565921658. This method may further comprise the step of obtaining amolecular marker profile of soybean variety 179565921658 and using themolecular marker profile to select for a progeny plant with the desiredtrait and the molecular marker profile of soybean cultivar 179565921658.In one embodiment, the desired trait is a mutant gene, gene, ortransgene present in the donor parent.

Recurrent Selection and Mass Selection

Recurrent selection is a method used in a plant breeding program toimprove a population of plants. Soybean cultivar 179565921658 issuitable for use in a recurrent selection program. The method entailsindividual plants cross pollinating with each other to form progeny. Theprogeny are grown and the superior progeny selected by any number ofselection methods, which include individual plant, half-sib progeny,full-sib progeny, and selfed progeny. The selected progeny are crosspollinated with each other to form progeny for another population. Thispopulation is planted and again superior plants are selected to crosspollinate with each other. Recurrent selection is a cyclical process andtherefore can be repeated as many times as desired. The objective ofrecurrent selection is to improve the traits of a population. Theimproved population can then be used as a source of breeding material toobtain new varieties for commercial or breeding use, including theproduction of a synthetic cultivar. A synthetic cultivar is theresultant progeny formed by the intercrossing of several selectedvarieties.

Mass selection is a useful technique when used in conjunction withmolecular marker enhanced selection. In mass selection, seeds fromindividuals are selected based on phenotype or genotype. These selectedseeds are then bulked and used to grow the next generation. Bulkselection requires growing a population of plants in a bulk plot,allowing the plants to self-pollinate, harvesting the seed in bulk, andthen using a sample of the seed harvested in bulk to plant the nextgeneration. Also, instead of self-pollination, directed pollinationcould be used as part of the breeding program.

Mass and recurrent selections can be used to improve populations ofeither self- or cross-pollinating crops. A genetically variablepopulation of heterozygous individuals is either identified, or created,by intercrossing several different parents. The plants are selectedbased on individual superiority, outstanding progeny, or excellentcombining ability. The selected plants are intercrossed to produce a newpopulation in which further cycles of selection are continued.

Single-Seed Descent

The single-seed descent procedure in the strict sense refers to plantinga segregating population, harvesting a sample of one seed per plant, andusing the one-seed sample to plant the next generation. When thepopulation has been advanced from the F₂ to the desired level ofinbreeding, the plants from which lines are derived will each trace todifferent F₂ individuals. The number of plants in a population declineseach generation due to failure of some seeds to germinate or some plantsto produce at least one seed. As a result, not all of the F₂ plantsoriginally sampled in the population will be represented by a progenywhen generation advance is completed.

Multiple-Seed Procedure

In a multiple-seed procedure, soybean breeders commonly harvest one ormore pods from each plant in a population and thresh them together toform a bulk. Part of the bulk is used to plant the next generation andpart is put in reserve. The procedure has been referred to as modifiedsingle-seed descent or the pod-bulk technique.

The multiple-seed procedure has been used to save labor at harvest. Itis considerably faster to thresh pods with a machine than to remove oneseed from each by hand for the single-seed procedure. The multiple-seedprocedure also makes it possible to plant the same number of seeds of apopulation in each generation of inbreeding. Enough seeds are harvestedto make up for those plants that did not germinate or produce seed.

Mutation Breeding

Mutation breeding is another method of introducing new traits intosoybean variety 179565921658. Mutations that occur spontaneously or areartificially induced can be useful sources of variability for a plantbreeder. The goal of artificial mutagenesis is to increase the rate ofmutation for a desired characteristic. Mutation rates can be increasedby many different means including temperature, long-term seed storage,tissue culture conditions, radiation; such as X-rays, Gamma rays (e.g.,cobalt 60 or cesium 137), neutrons, (product of nuclear fission byuranium 235 in an atomic reactor), Beta radiation (emitted fromradioisotopes such as phosphorus 32 or carbon 14), or ultravioletradiation (preferably from 2500 to 2900 nm), or chemical mutagens (suchas base analogues (5-bromo-uracil)), related compounds (8-ethoxycaffeine), antibiotics (streptonigrin), alkylating agents (sulfurmustards, nitrogen mustards, epoxides, ethylenamines, sulfates,sulfonates, sulfones, lactones), azide, hydroxylamine, nitrous acid, oracridines. Once a desired trait is observed through mutagenesis thetrait may then be incorporated into existing germplasm by traditionalbreeding techniques. Details of mutation breeding can be found in Fehr,“Principles of Cultivar Development,” Macmillan Publishing Company(1993). In addition, mutations created in other soybean plants may beused to produce a backcross conversion of soybean cultivar 179565921658that comprises such mutation.

Additional methods include, but are not limited to, expression vectorsintroduced into plant tissues using a direct gene transfer method, suchas microprojectile-mediated delivery, DNA injection, electroporation,and the like. More preferably, expression vectors are introduced intoplant tissues by using either microprojectile-mediated delivery with abiolistic device or by using Agrobacterium-mediated transformation.Transformant plants obtained with the protoplasm of the embodiments areintended to be within the scope of the embodiments.

Single-Gene Conversions

When the term “soybean plant” is used in the context of an embodiment,this also includes any single gene conversions of that variety. The termsingle gene converted plant as used herein refers to those soybeanplants which are developed by a plant breeding technique calledbackcrossing wherein essentially all of the desired morphological andphysiological characteristics of a variety are recovered in addition tothe single gene transferred into the variety via the backcrossingtechnique. Backcrossing methods can be used with one embodiment toimprove or introduce a characteristic into the variety. The term“backcrossing” as used herein refers to the repeated crossing of ahybrid progeny back to the recurrent parent, i.e., backcrossing 1, 2, 3,4, 5, 6, 7, 8, or more times to the recurrent parent. The parentalsoybean plant that contributes the gene for the desired characteristicis termed the nonrecurrent or donor parent. This terminology refers tothe fact that the nonrecurrent parent is used one time in the backcrossprotocol and therefore does not recur. The parental soybean plant towhich the gene or genes from the nonrecurrent parent are transferred isknown as the recurrent parent as it is used for several rounds in thebackcrossing protocol (Poehlman & Sleper (1994); Fehr, Principles ofCultivar Development, pp. 261-286 (1987)). In a typical backcrossprotocol, the original variety of interest (recurrent parent) is crossedto a second variety (nonrecurrent parent) that carries the single geneof interest to be transferred. The resulting progeny from this cross arethen crossed again to the recurrent parent and the process is repeateduntil a soybean plant is obtained wherein essentially all of the desiredmorphological and physiological characteristics of the recurrent parentare recovered in the converted plant, in addition to the singletransferred gene from the nonrecurrent parent.

The selection of a suitable recurrent parent is an important step for asuccessful backcrossing procedure. The goal of a backcross protocol isto alter or substitute a single trait or characteristic in the originalvariety. To accomplish this, a single gene of the recurrent variety ismodified or substituted with the desired gene from the nonrecurrentparent, while retaining essentially all of the rest of the desiredgenetic, and therefore the desired physiological and morphologicalconstitution of the original variety. The choice of the particularnonrecurrent parent will depend on the purpose of the backcross; one ofthe major purposes is to add some agronomically important trait to theplant. The exact backcrossing protocol will depend on the characteristicor trait being altered to determine an appropriate testing protocol.Although backcrossing methods are simplified when the characteristicbeing transferred is a dominant allele, a recessive allele may also betransferred. In this instance, it may be necessary to introduce a testof the progeny to determine if the desired characteristic has beensuccessfully transferred.

Many single gene traits have been identified that are not regularlyselected for in the development of a new variety but that can beimproved by backcrossing techniques. Single gene traits may or may notbe transgenic. Examples of these traits include, but are not limited to,male sterility, waxy starch, herbicide resistance, resistance forbacterial, fungal, or viral disease, insect resistance, male fertility,enhanced nutritional quality, industrial usage, yield stability, andyield enhancement. These genes are generally inherited through thenucleus. Several of these single gene traits are described in U.S. Pat.Nos. 5,959,185, 5,973,234, and 5,977,445, the disclosures of which arespecifically hereby incorporated by reference.

Introduction of a New Trait or Locus into Soybean Cultivar 179565921658

Variety 179565921658 represents a new variety into which a new locus ortrait may be introgressed. Direct transformation and backcrossingrepresent two important methods that can be used to accomplish such anintrogression. The term backcross conversion and single locus conversionare used interchangeably to designate the product of a backcrossingprogram.

Backcross Conversions of Soybean Cultivar 179565921658

A backcross conversion of soybean cultivar 179565921658 occurs when DNAsequences are introduced through backcrossing (Hallauer, et al., “CornBreeding,” Corn and Corn Improvements, No. 18, pp. 463-481 (1988)), withsoybean cultivar 179565921658 utilized as the recurrent parent. Bothnaturally occurring and transgenic DNA sequences may be introducedthrough backcrossing techniques. A backcross conversion may produce aplant with a trait or locus conversion in at least two or morebackcrosses, including at least 2 crosses, at least 3 crosses, at least4 crosses, at least 5 crosses, and the like. Molecular marker assistedbreeding or selection may be utilized to reduce the number ofbackcrosses necessary to achieve the backcross conversion. For example,see, Openshaw, S. J., et al., Marker-assisted Selection in BackcrossBreeding, Proceedings Symposium of the Analysis of Molecular Data, CropScience Society of America, Corvallis, Oreg. (August 1994), where it isdemonstrated that a backcross conversion can be made in as few as twobackcrosses.

The complexity of the backcross conversion method depends on the type oftrait being transferred (single genes or closely linked genes ascompared to unlinked genes), the level of expression of the trait, thetype of inheritance (cytoplasmic or nuclear), and the types of parentsincluded in the cross. It is understood by those of ordinary skill inthe art that for single gene traits that are relatively easy toclassify, the backcross method is effective and relatively easy tomanage. (See, Hallauer, et al., Corn and Corn Improvement, Sprague andDudley, Third Ed. (1998)). Desired traits that may be transferredthrough backcross conversion include, but are not limited to, sterility(nuclear and cytoplasmic), fertility restoration, nutritionalenhancements, drought tolerance, nitrogen utilization, altered fattyacid profile, low phytate, industrial enhancements, disease resistance(bacterial, fungal, or viral), insect resistance, and herbicideresistance. In addition, an introgression site itself, such as an FRTsite, Lox site, or other site-specific integration site, may be insertedby backcrossing and utilized for direct insertion of one or more genesof interest into a specific plant variety. In some embodiments, thenumber of loci that may be backcrossed into soybean cultivar179565921658 is at least 1, 2, 3, 4, or 5, and/or no more than 6, 5, 4,3, or 2. A single locus may contain several transgenes, such as atransgene for disease resistance that, in the same expression vector,also contains a transgene for herbicide resistance. The gene forherbicide resistance may be used as a selectable marker and/or as aphenotypic trait. A single locus conversion of site specific integrationsystem allows for the integration of multiple genes at the convertedloci.

The backcross conversion may result from either the transfer of adominant allele or a recessive allele. Selection of progeny containingthe trait of interest is accomplished by direct selection for a traitassociated with a dominant allele. Transgenes transferred viabackcrossing typically function as a dominant single gene trait and arerelatively easy to classify. Selection of progeny for a trait that istransferred via a recessive allele requires growing and selfing thefirst backcross generation to determine which plants carry the recessivealleles. Recessive traits may require additional progeny testing insuccessive backcross generations to determine the presence of the locusof interest. The last backcross generation is usually selfed to givepure breeding progeny for the gene(s) being transferred, although abackcross conversion with a stably introgressed trait may also bemaintained by further backcrossing to the recurrent parent withselection for the converted trait.

Along with selection for the trait of interest, progeny are selected forthe phenotype of the recurrent parent. The backcross is a form ofinbreeding, and the features of the recurrent parent are automaticallyrecovered after successive backcrosses. Poehlman, Breeding Field Crops,p. 204 (1987). Poehlman suggests from one to four or more backcrosses,but as noted above, the number of backcrosses necessary can be reducedwith the use of molecular markers. Other factors, such as a geneticallysimilar donor parent, may also reduce the number of backcrossesnecessary. As noted by Poehlman, backcrossing is easiest for simplyinherited, dominant, and easily recognized traits.

One process for adding or modifying a trait or locus in soybean variety179565921658 comprises crossing soybean cultivar 179565921658 plantsgrown from soybean cultivar 179565921658 seed with plants of anothersoybean variety that comprise the desired trait or locus, selecting F₁progeny plants that comprise the desired trait or locus to produceselected F₁ progeny plants, crossing the selected progeny plants withthe soybean cultivar 179565921658 plants to produce backcross progenyplants, selecting for backcross progeny plants that have the desiredtrait or locus and the morphological characteristics of soybean variety179565921658 to produce selected backcross progeny plants, andbackcrossing to soybean cultivar 179565921658 three or more times insuccession to produce selected fourth or higher backcross progeny plantsthat comprise said trait or locus. The modified soybean cultivar179565921658 may be further characterized as having the physiologicaland morphological characteristics of soybean variety 179565921658 listedin Table 1 as determined at the 5% significance level when grown in thesame environmental conditions and/or may be characterized by percentsimilarity or identity to soybean cultivar 179565921658 as determined bySSR markers. The above method may be utilized with fewer backcrosses inappropriate situations, such as when the donor parent is highly relatedor markers are used in the selection step. Desired traits that may beused include those nucleic acids known in the art, some of which arelisted herein, that will affect traits through nucleic acid expressionor inhibition. Desired loci include the introgression of FRT, Lox, andother sites for site specific integration, which may also affect adesired trait if a functional nucleic acid is inserted at theintegration site.

In addition, the above process and other similar processes describedherein may be used to produce first generation progeny soybean seed byadding a step at the end of the process that comprises crossing soybeancultivar 179565921658 with the introgressed trait or locus with adifferent soybean plant and harvesting the resultant first generationprogeny soybean seed.

Molecular Techniques Using Soybean Cultivar 179565921658

The advent of new molecular biological techniques has allowed theisolation and characterization of genetic elements with specificfunctions, such as encoding specific protein products. Scientists in thefield of plant biology developed a strong interest in engineering thegenome of plants to contain and express foreign genetic elements, oradditional, or modified versions of native or endogenous geneticelements in order to “alter” (the utilization of up-regulation,down-regulation, or gene silencing) the traits of a plant in a specificmanner. Any DNA sequences, whether from a different species or from thesame species, which are introduced into the genome using transformationor various breeding methods are referred to herein collectively as“transgenes.” In some embodiments, a transgenic variant of soybeancultivar 179565921658 may contain at least one transgene but couldcontain at least 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, and/or no more than 15,14, 13, 12, 11, 10, 9, 8, 7, 6, 5, 4, 3, or 2. Over the last fifteen totwenty years several methods for producing transgenic plants have beendeveloped, and another embodiment also relates to transgenic variants ofthe claimed soybean variety 179565921658.

Nucleic acids or polynucleotides refer to RNA or DNA that is linear orbranched, single or double stranded, or a hybrid thereof. The term alsoencompasses RNA/DNA hybrids. These terms also encompass untranslatedsequence located at both the 3′ and 5′ ends of the coding region of thegene: at least about 1000 nucleotides of sequence upstream from the 5′end of the coding region and at least about 200 nucleotides of sequencedownstream from the 3′ end of the coding region of the gene. Less commonbases, such as inosine, 5-methylcytosine, 6-methyladenine, hypoxanthineand others can also be used for antisense, dsRNA and ribozyme pairing.For example, polynucleotides that contain C-5 propyne analogues ofuridine and cytidine have been shown to bind RNA with high affinity andto be potent antisense inhibitors of gene expression. Othermodifications, such as modification to the phosphodiester backbone, orthe 2′-hydroxy in the ribose sugar group of the RNA can also be made.The antisense polynucleotides and ribozymes can consist entirely ofribonucleotides, or can contain mixed ribonucleotides anddeoxyribonucleotides. The polynucleotides of the embodiments may beproduced by any means, including genomic preparations, cDNApreparations, in-vitro synthesis, RT-PCR, and in vitro or in vivotranscription.

One embodiment is a process for producing soybean variety 179565921658further comprising a desired trait, said process comprising introducinga transgene that confers a desired trait to a soybean plant of variety179565921658. Another embodiment is the product produced by thisprocess. In one embodiment the desired trait may be one or more ofherbicide resistance, insect resistance, disease resistance, decreasedphytate, or modified fatty acid or carbohydrate metabolism. The specificgene may be any known in the art or listed herein, including: apolynucleotide conferring resistance to imidazolinone, dicamba,sulfonylurea, glyphosate, glufosinate, triazine, PPO-inhibitorherbicides, benzonitrile, cyclohexanedione, phenoxy proprionic acid, andL-phosphinothricin; a polynucleotide encoding a Bacillus thuringiensispolypeptide; a polynucleotide encoding phytase, FAD-2, FAD-3, galactinolsynthase, or a raffinose synthetic enzyme; or a polynucleotideconferring resistance to soybean cyst nematode, brown stem rot,Phytophthora root rot, soybean mosaic virus, or sudden death syndrome.

Numerous methods for plant transformation have been developed, includingbiological and physical plant transformation protocols. See, forexample, Miki et al., “Procedures for Introducing Foreign DNA intoPlants,” in Methods in Plant Molecular Biology and Biotechnology, Glickand Thompson Eds., CRC Press, Inc., Boca Raton, pp. 67-88 (1993), andArmstrong, “The First Decade of Maize Transformation: A Review andFuture Perspective,” Maydica, 44:101-109 (1999). In addition, expressionvectors and in vitro culture methods for plant cell or tissuetransformation and regeneration of plants are available. See, forexample, Gruber, et al., “Vectors for Plant Transformation,” in Methodsin Plant Molecular Biology and Biotechnology, Glick and Thompson Eds.,CRC Press, Inc., Boca Raton, pp. 89-119 (1993).

A genetic trait which has been engineered into the genome of aparticular soybean plant may then be moved into the genome of anothervariety using traditional breeding techniques that are well known in theplant breeding arts. For example, a backcrossing approach is commonlyused to move a transgene from a transformed soybean variety into analready developed soybean variety, and the resulting backcrossconversion plant would then comprise the transgene(s).

Various genetic elements can be introduced into the plant genome usingtransformation. These elements include, but are not limited to, genes,coding sequences, inducible, constitutive and tissue specific promoters,enhancing sequences, and signal and targeting sequences. For example,see the traits, genes, and transformation methods listed in U.S. Pat.No. 6,118,055.

Breeding with Molecular Markers

Molecular markers, which includes markers identified through the use oftechniques such as Isozyme Electrophoresis, Restriction Fragment LengthPolymorphisms (RFLPs), Randomly Amplified Polymorphic DNAs (RAPDs),Arbitrarily Primed Polymerase Chain Reaction (AP-PCR), DNA AmplificationFingerprinting (DAF), Sequence Characterized Amplified Regions (SCARs),Amplified Fragment Length Polymorphisms (AFLPs), Simple Sequence Repeats(SSRs), and Single Nucleotide Polymorphisms (SNPs), may be used in plantbreeding methods utilizing soybean cultivar 179565921658.

Isozyme Electrophoresis and RFLPs have been widely used to determinegenetic composition. Shoemaker and Olsen, Molecular Linkage Map ofSoybean (Glycine max L. Men.), pp. 6.131-6.138 (1993). In S. J. O'Brien(ed.), Genetic Maps: Locus Maps of Complex Genomes, Cold Spring HarborLaboratory Press, Cold Spring Harbor, N.Y., developed a moleculargenetic linkage map that consisted of 25 linkage groups with about 365RFLP, 11 RAPD (random amplified polymorphic DNA), 3 classical markers,and 4 isozyme loci. See also, Shoemaker, R. C., 1994 RFLP Map ofSoybean, pp. 299-309; In R. L. Phillips and I. K. Vasil (ed.), DNA-basedmarkers in plants, Kluwer Academic Press Dordrecht, the Netherlands.

SSR technology is currently the most efficient and practical markertechnology. More marker loci can be routinely used, and more alleles permarker locus can be found, using SSRs in comparison to RFLPs. Forexample, Diwan and Cregan described highly polymorphic microsatelliteloci in soybean with as many as 26 alleles. (Diwan, N., and Cregan. P.B., Automated sizing of fluorescent-labeled simple sequence repeat (SSR)markers to assay genetic variation in Soybean, Theor. Appl. Genet.,95:220-225 (1997)). Single Nucleotide Polymorphisms may also be used toidentify the unique genetic composition of the embodiment(s) and progenyvarieties retaining that unique genetic composition. Various molecularmarker techniques may be used in combination to enhance overallresolution.

Soybean DNA molecular marker linkage maps have been rapidly constructedand widely implemented in genetic studies. One such study is describedin Cregan, et. al, “An Integrated Genetic Linkage Map of the SoybeanGenome,” Crop Science, 39:1464-1490 (1999). Sequences and PCR conditionsof SSR Loci in Soybean, as well as the most current genetic map, may befound in Soybase on the World Wide Web.

One use of molecular markers is Quantitative Trait Loci (QTL) mapping.QTL mapping is the use of markers, which are known to be closely linkedto alleles that have measurable effects on a quantitative trait.Selection in the breeding process is based upon the accumulation ofmarkers linked to the positive effecting alleles and/or the eliminationof the markers linked to the negative effecting alleles from the plant'sgenome.

Molecular markers can also be used during the breeding process for theselection of qualitative traits. For example, markers closely linked toalleles or markers containing sequences within the actual alleles ofinterest can be used to select plants that contain the alleles ofinterest during a backcrossing breeding program. The markers can also beused to select for the genome of the recurrent parent and against thegenome of the donor parent. Using this procedure can minimize the amountof genome from the donor parent that remains in the selected plants. Itcan also be used to reduce the number of crosses back to the recurrentparent needed in a backcrossing program. The use of molecular markers inthe selection process is often called genetic marker enhanced selection.Molecular markers may also be used to identify and exclude certainsources of germplasm as parental varieties or ancestors of a plant byproviding a means of tracking genetic profiles through crosses.

Production of Double Haploids

The production of double haploids can also be used for the developmentof plants with a homozygous phenotype in the breeding program. Forexample, a soybean plant for which soybean cultivar 179565921658 is aparent can be used to produce double haploid plants. Double haploids areproduced by the doubling of a set of chromosomes (1N) from aheterozygous plant to produce a completely homozygous individual. Forexample, see, Wan, et al., “Efficient Production of Doubled HaploidPlants Through Colchicine Treatment of Anther-Derived Maize Callus,”Theoretical and Applied Genetics, 77:889-892 (1989) and U.S. Pat. No.7,135,615. This can be advantageous because the process omits thegenerations of selfing needed to obtain a homozygous plant from aheterozygous source.

Haploid induction systems have been developed for various plants toproduce haploid tissues, plants and seeds. The haploid induction systemcan produce haploid plants from any genotype by crossing a selected line(as female) with an inducer line. Such inducer lines for maize includeStock 6 (Coe, Am. Nat., 93:381-382 (1959); Sharkar and Coe, Genetics,54:453-464 (1966); KEMS (Deimling, Roeber, and Geiger, Vortr.Pflanzenzuchtg, 38:203-224 (1997); or KMS and ZMS (Chalyk, Bylich &Chebotar, MNL, 68:47 (1994); Chalyk & Chebotar, Plant Breeding,119:363-364 (2000)); and indeterminate gametophyte (ig) mutation(Kermicle, Science, 166:1422-1424 (1969)). The disclosures of which areincorporated herein by reference.

Methods for obtaining haploid plants are also disclosed in Kobayashi,M., et al., Journ. of Heredity, 71(1):9-14 (1980); Pollacsek, M.,Agronomie (Paris) 12(3):247-251 (1992); Cho-Un-Haing, et al., Journ. ofPlant Biol., 39(3):185-188 (1996); Verdoodt, L., et al., 96(2):294-300(February 1998); Chalyk, et al., Maize Genet Coop., Newsletter 68:47(1994).

Thus, an embodiment is a process for making a substantially homozygoussoybean cultivar 179565921658 progeny plant by producing or obtaining aseed from the cross of soybean cultivar 179565921658 and another soybeanplant and applying double haploid methods to the F₁ seed or F₁ plant orto any successive filial generation. Based on studies in maize andcurrently being conducted in soybean, such methods would decrease thenumber of generations required to produce a variety with similargenetics or characteristics to soybean cultivar 179565921658. See,Bernardo, R. and Kahler, A. L., Theor. Appl. Genet., 102:986-992 (2001).

In particular, a process of making seed retaining the molecular markerprofile of soybean variety 179565921658 is contemplated, such processcomprising obtaining or producing Ft seed for which soybean variety179565921658 is a parent, inducing doubled haploids to create progenywithout the occurrence of meiotic segregation, obtaining the molecularmarker profile of soybean variety 179565921658, and selecting progenythat retain the molecular marker profile of soybean cultivar179565921658.

Descriptions of other breeding methods that are commonly used fordifferent traits and crops can be found in one of several referencebooks (e.g., Allard (1960); Simmonds (1979); Sneep, et al. (1979); Fehr(1987))

Expression Vectors for Soybean Transformation: Marker Genes

Plant transformation involves the construction of an expression vectorwhich will function in plant cells. Such a vector comprises DNAcomprising a gene under control of, or operatively linked to, aregulatory element (for example, a promoter). Expression vectors includeat least one genetic marker operably linked to a regulatory element (forexample, a promoter) that allows transformed cells containing the markerto be either recovered by negative selection, i.e., inhibiting growth ofcells that do not contain the selectable marker gene, or by positiveselection, i.e., screening for the product encoded by the geneticmarker. Many commonly used selectable marker genes for planttransformation are well-known in the transformation arts, and include,for example, genes that code for enzymes that metabolically detoxify aselective chemical agent which may be an antibiotic or an herbicide, orgenes that encode an altered target which is insensitive to theinhibitor. A few positive selection methods are also known in the art.

One commonly used selectable marker gene for plant transformation is theneomycin phosphotransferase II (nptII) gene which, when under thecontrol of plant regulatory signals, confers resistance to kanamycin.Fraley, et al., Proc. Natl. Acad. Sci. USA, 80:4803 (1983).

Another commonly used selectable marker gene is the hygromycinphosphotransferase gene which confers resistance to the antibiotichygromycin. Vanden Elzen, et al., Plant Mol. Biol., 5:299 (1985).

Additional selectable marker genes of bacterial origin that conferresistance to antibiotics include gentamycin acetyl transferase,streptomycin phosphotransferase and aminoglycoside-3′-adenyltransferase, the bleomycin resistance determinant (Hayford, et al.,Plant Physiol., 86:1216 (1988); Jones, et al., Mol. Gen. Genet., 210:86(1987); Svab, et al., Plant Mol. Biol., 14:197 (1990); Hille, et al.,Plant Mol. Biol., 7:171 (1986)). Other selectable marker genes conferresistance to herbicides such as glyphosate, glufosinate, or bromoxynil(Comai, et al., Nature, 317:741-744 (1985); Gordon-Kamm, et al., PlantCell, 2:603-618 (1990); Stalker, et al., Science, 242:419-423 (1988)).

Selectable marker genes for plant transformation not of bacterial origininclude, for example, mouse dihydrofolate reductase, plant5-enolpyruvylshikimate-3-phosphate synthase, and plant acetolactatesynthase (Eichholtz, et al., Somatic Cell Mol. Genet., 13:67 (1987);Shah, et al., Science, 233:478 (1986); Charest, et al., Plant Cell Rep.,8:643 (1990)).

Another class of marker genes for plant transformation requiresscreening of presumptively transformed plant cells, rather than directgenetic selection of transformed cells, for resistance to a toxicsubstance such as an antibiotic. These genes are particularly useful toquantify or visualize the spatial pattern of expression of a gene inspecific tissues and are frequently referred to as reporter genesbecause they can be fused to a gene or gene regulatory sequence for theinvestigation of gene expression. Commonly used genes for screeningpresumptively transformed cells include β-glucuronidase (GUS),β-galactosidase, luciferase, and chloramphenicol acetyltransferase(Jefferson, R. A., Plant Mol. Biol. Rep., 5:387 (1987); Teeri, et al.,EMBO J., 8:343 (1989); Koncz, et al., Proc. Natl. Acad. Sci. USA, 84:131(1987); DeBlock, et al., EMBO J., 3:1681 (1984)).

In vivo methods for visualizing GUS activity that do not requiredestruction of plant tissue are available (Molecular Probes, Publication2908, IMAGENE GREEN, pp. 1-4 (1993); Naleway, et al., J. Cell Biol.,115:151a (1991)). However, these in-vivo methods for visualizing GUSactivity have not proven useful for recovery of transformed cellsbecause of low sensitivity, high fluorescent backgrounds, andlimitations associated with the use of luciferase genes as selectablemarkers.

More recently, a gene encoding Green Fluorescent Protein (GFP) has beenutilized as a marker for gene expression in prokaryotic and eukaryoticcells (Chalfie, et al., Science, 263:802 (1994)). GFP and mutants of GFPmay be used as screenable markers.

Expression Vectors for Soybean Transformation: Promoters

Genes included in expression vectors must be driven by a nucleotidesequence comprising a regulatory element (for example, a promoter).Several types of promoters are well known in the transformation arts asare other regulatory elements that can be used alone or in combinationwith promoters.

As used herein, “promoter” includes reference to a region of DNAupstream from the start of transcription and involved in recognition andbinding of RNA polymerase and other proteins to initiate transcription.A “plant promoter” is a promoter capable of initiating transcription inplant cells. Examples of promoters under developmental control includepromoters that preferentially initiate transcription in certain tissues,such as leaves, roots, seeds, fibers, xylem vessels, tracheids, orsclerenchyma. Such promoters are referred to as “tissue-preferred.”Promoters that initiate transcription only in a certain tissue arereferred to as “tissue-specific.” A “cell-type” specific promoterprimarily drives expression in certain cell types in one or more organs,for example, vascular cells in roots or leaves. An “inducible” promoteris a promoter which is under environmental control. Examples ofenvironmental conditions that may effect transcription by induciblepromoters include anaerobic conditions or the presence of light.Tissue-specific, tissue-preferred, cell-type specific, and induciblepromoters constitute the class of “non-constitutive” promoters. A“constitutive” promoter is a promoter that is active under mostenvironmental conditions.

A. Inducible Promoters: An inducible promoter is operably linked to agene for expression in soybean. Optionally, the inducible promoter isoperably linked to a nucleotide sequence encoding a signal sequencewhich is operably linked to a gene for expression in soybean. With aninducible promoter the rate of transcription increases in response to aninducing agent.

Any inducible promoter can be used in an embodiment(s). See, Ward, etal., Plant Mol. Biol., 22:361-366 (1993). Exemplary inducible promotersinclude, but are not limited to, that from the ACEI system whichresponds to copper (Mett, et al., Proc. Natl. Acad. Sci. USA,90:4567-4571 (1993)); In2 gene from maize which responds tobenzenesulfonamide herbicide safeners (Hershey, et al., Mol. GenGenetics, 227:229-237 (1991); Gatz, et al., Mol. Gen. Genetics,243:32-38 (1994)); or Tet repressor from Tn10 (Gatz, et al., Mol. Gen.Genetics, 227:229-237 (1991)). An inducible promoter is a promoter thatresponds to an inducing agent to which plants do not normally respond.An exemplary inducible promoter is the inducible promoter from a steroidhormone gene, the transcriptional activity of which is induced by aglucocorticosteroid hormone (Schena, et al., Proc. Natl. Acad. Sci. USA,88:0421 (1991)).

B. Constitutive Promoters: A constitutive promoter is operably linked toa gene for expression in soybean or the constitutive promoter isoperably linked to a nucleotide sequence encoding a signal sequencewhich is operably linked to a gene for expression in soybean.

Many different constitutive promoters can be utilized in anembodiment(s). Exemplary constitutive promoters include, but are notlimited to, the promoters from plant viruses such as the 35S promoterfrom CaMV (Odell, et al., Nature, 313:810-812 (1985)) and the promotersfrom such genes as rice actin (McElroy, et al., Plant Cell, 2:163-171(1990)); ubiquitin (Christensen, et al., Plant Mol. Biol., 12:619-632(1989); Christensen, et al., Plant Mol. Biol., 18:675-689 (1992)); pEMU(Last, et al., Theor. Appl. Genet., 81:581-588 (1991)); MAS (Velten, etal., EMBO J., 3:2723-2730 (1984)); and maize H3 histone (Lepetit, etal., Mol. Gen. Genetics, 231:276-285 (1992); Atanassova, et al., PlantJournal, 2 (3):291-300 (1992)). The ALS promoter, XbaI/NcoI fragment 5′to the Brassica napus ALS3 structural gene (or a nucleotide sequencesimilarity to said XbaI/NcoI fragment), represents a particularly usefulconstitutive promoter. See, U.S. Pat. No. 5,659,026.

C. Tissue-Specific or Tissue-Preferred Promoters: A tissue-specificpromoter is operably linked to a gene for expression in soybean.Optionally, the tissue-specific promoter is operably linked to anucleotide sequence encoding a signal sequence which is operably linkedto a gene for expression in soybean. Plants transformed with a gene ofinterest operably linked to a tissue-specific promoter produce theprotein product of the transgene exclusively, or preferentially, in aspecific tissue.

Any tissue-specific or tissue-preferred promoter can be utilized in anembodiment(s). Exemplary tissue-specific or tissue-preferred promotersinclude, but are not limited to, a root-preferred promoter such as thatfrom the phaseolin gene (Murai, et al., Science, 23:476-482 (1983);Sengupta-Gopalan, et al., Proc. Natl. Acad. Sci. USA, 82:3320-3324(1985)); a leaf-specific and light-induced promoter such as that fromcab or rubisco (Simpson, et al., EMBO J., 4(11):2723-2729 (1985); Timko,et al., Nature, 318:579-582 (1985)); an anther-specific promoter such asthat from LAT52 (Twell, et al., Mol. Gen. Genetics, 217:240-245 (1989));a pollen-specific promoter such as that from Zm13 (Guerrero, et al.,Mol. Gen. Genetics, 244:161-168 (1993)); or a microspore-preferredpromoter such as that from apg (Twell, et al., Sex. Plant Reprod.,6:217-224 (1993)).

Signal Sequences for Targeting Proteins to Subcellular Compartments

Transport of a protein produced by transgenes to a subcellularcompartment, such as the chloroplast, vacuole, peroxisome, glyoxysome,cell wall, or mitochondrion, or for secretion into the apoplast, isaccomplished by means of operably linking the nucleotide sequenceencoding a signal sequence to the 5′ and/or 3′ region of a gene encodingthe protein of interest. Targeting sequences at the 5′ and/or 3′ end ofthe structural gene may determine during protein synthesis andprocessing where the encoded protein is ultimately compartmentalized.

The presence of a signal sequence directs a polypeptide to either anintracellular organelle or subcellular compartment or for secretion tothe apoplast. Many signal sequences are known in the art. See, forexample, Becker, et al., Plant Mol. Biol., 20:49 (1992); Knox, C., etal., Plant Mol. Biol., 9:3-17 (1987); Lerner, et al., Plant Physiol.,91:124-129 (1989); Frontes, et al., Plant Cell, 3:483-496 (1991);Matsuoka, et al., Proc. Natl. Acad. Sci., 88:834 (1991); Gould, et al.,J. Cell. Biol., 108:1657 (1989); Creissen, et al., Plant J., 2:129(1991); Kalderon, et al., Cell, 39:499-509 (1984); Steifel, et al.,Plant Cell, 2:785-793 (1990).

Foreign Protein Genes and Agronomic Genes: Transformation

With transgenic plants according to one embodiment, a foreign proteincan be produced in commercial quantities. Thus, techniques for theselection and propagation of transformed plants, which are wellunderstood in the art, yield a plurality of transgenic plants which areharvested in a conventional manner, and a foreign protein can then beextracted from a tissue of interest or from total biomass. Proteinextraction from plant biomass can be accomplished by known methods whichare discussed, for example, by Heney and Orr, Anal. Biochem., 114:92-6(1981).

According to an embodiment, the transgenic plant provided for commercialproduction of foreign protein is a soybean plant. In another embodiment,the biomass of interest is seed. For the relatively small number oftransgenic plants that show higher levels of expression, a genetic mapcan be generated, primarily via conventional RFLP, PCR, and SSRanalysis, which identifies the approximate chromosomal location of theintegrated DNA molecule. For exemplary methodologies in this regard,see, Glick and Thompson, Methods in Plant Molecular Biology andBiotechnology, CRC Press, Inc., Boca Raton, 269:284 (1993). Mapinformation concerning chromosomal location is useful for proprietaryprotection of a subject transgenic plant.

Wang, et al. discuss “Large Scale Identification, Mapping and Genotypingof Single-Nucleotide Polymorphisms in the Human Genome,” Science,280:1077-1082 (1998), and similar capabilities are becoming increasinglyavailable for the soybean genome. Map information concerning chromosomallocation is useful for proprietary protection of a subject transgenicplant. If unauthorized propagation is undertaken and crosses made withother germplasm, the map of the integration region can be compared tosimilar maps for suspect plants to determine if the latter have a commonparentage with the subject plant. Map comparisons would involvehybridizations, RFLP, PCR, SSR, and sequencing, all of which areconventional techniques. SNPs may also be used alone or in combinationwith other techniques.

Likewise, by means of one embodiment, plants can be geneticallyengineered to express various phenotypes of agronomic interest. Throughthe transformation of soybean, the expression of genes can be altered toenhance disease resistance, insect resistance, herbicide resistance,agronomic, grain quality, and other traits. Transformation can also beused to insert DNA sequences which control or help controlmale-sterility. DNA sequences native to soybean, as well as non-nativeDNA sequences, can be transformed into soybean and used to alter levelsof native or non-native proteins. Various promoters, targetingsequences, enhancing sequences, and other DNA sequences can be insertedinto the genome for the purpose of altering the expression of proteins.The interruption or suppression of the expression of a gene at the levelof transcription or translation (also known as gene silencing or genesuppression) is desirable for several aspects of genetic engineering inplants.

Many techniques for gene silencing are well-known to one of skill in theart, including, but not limited to, knock-outs (such as by insertion ofa transposable element such as Mu (Vicki Chandler, The Maize Handbook,Ch. 118 (Springer-Verlag 1994)) or other genetic elements such as a FRT,Lox, or other site specific integration sites; antisense technology(see, e.g., Sheehy, et al., PNAS USA, 85:8805-8809 (1988) and U.S. Pat.Nos. 5,107,065, 5,453,566, and 5,759,829); co-suppression (e.g., Taylor,Plant Cell, 9:1245 (1997); Jorgensen, Trends Biotech., 8(12):340-344(1990); Flavell, PNAS USA, 91:3490-3496 (1994); Finnegan, et al.,Bio/Technology, 12:883-888 (1994); Neuhuber, et al., Mol. Gen. Genet.,244:230-241 (1994)); RNA interference (Napoli, et al., Plant Cell,2:279-289 (1990); U.S. Pat. No. 5,034,323; Sharp, Genes Dev., 13:139-141(1999); Zamore, et al., Cell, 101:25-33 (2000); Montgomery, et al., PNASUSA, 95:15502-15507 (1998)), virus-induced gene silencing (Burton, etal., Plant Cell, 12:691-705 (2000); Baulcombe, Curr. Op. Plant Bio.,2:109-113 (1999)); target-RNA-specific ribozymes (Haseloff, et al.,Nature, 334:585-591 (1988)); hairpin structures (Smith, et al., Nature,407:319-320 (2000); U.S. Pat. Nos. 6,423,885, 7,138,565, 6,753,139, and7,713,715); MicroRNA (Aukerman & Sakai, Plant Cell, 15:2730-2741(2003)); ribozymes (Steinecke, et al., EMBO J., 11:1525 (1992);Perriman, et al., Antisense Res. Dev., 3:253 (1993)); oligonucleotidemediated targeted modification (e.g., U.S. Pat. Nos. 6,528,700 and6,911,575); Zn-finger targeted molecules (e.g., U.S. Pat. Nos.7,151,201, 6,453,242, 6,785,613, 7,177,766 and 7,788,044); and othermethods or combinations of the above methods known to those of skill inthe art.

Methods for Soybean Transformation

Numerous methods for plant transformation have been developed includingbiological and physical plant transformation protocols. See, forexample, Miki, et al., “Procedures for Introducing Foreign DNA intoPlants,” in Methods in Plant Molecular Biology and Biotechnology, Glickand Thompson Eds., CRC Press, Inc., Boca Raton, pp. 67-88 (1993). Inaddition, expression vectors and in-vitro culture methods for plant cellor tissue transformation and regeneration of plants are available. See,for example, Gruber, et al., “Vectors for Plant Transformation,” inMethods in Plant Molecular Biology and Biotechnology, Glick and ThompsonEds., CRC Press, Inc., Boca Raton, pp. 89-119 (1993).

A. Agrobacterium-mediated Transformation: One method for introducing anexpression vector into plants is based on the natural transformationsystem of Agrobacterium. See, for example, Horsch, et al., Science,227:1229 (1985). A. tumefaciens and A. rhizogenes are plant pathogenicsoil bacteria which genetically transform plant cells. The Ti and Riplasmids of A. tumefaciens and A. rhizogenes, respectively, carry genesresponsible for genetic transformation of the plant. See, for example,Kado, C. I., Crit. Rev. Plant Sci., 10:1 (1991). Descriptions ofAgrobacterium vector systems and methods for Agrobacterium-mediated genetransfer are provided by Gruber, et al., supra, Miki, et al., supra, andMoloney, et al., Plant Cell Reports, 8:238 (1989). See also, U.S. Pat.No. 5,563,055 (Townsend and Thomas), issued Oct. 8, 1996.

B. Direct Gene Transfer: Several methods of plant transformation,collectively referred to as direct gene transfer, have been developed asan alternative to Agrobacterium-mediated transformation. A generallyapplicable method of plant transformation is microprojectile-mediatedtransformation where DNA is carried on the surface of microprojectilesmeasuring 1 to 4 μm. The expression vector is introduced into planttissues with a biolistic device that accelerates the microprojectiles tospeeds of 300 to 600 m/s which is sufficient to penetrate plant cellwalls and membranes. Sanford, et al., Part. Sci. Technol., 5:27 (1987);Sanford, J. C., Trends Biotech., 6:299 (1988); Klein, et al., Bio/Tech.,6:559-563 (1988); Sanford, J. C., Physiol Plant, 7:206 (1990); Klein, etal., Biotechnology, 10:268 (1992). See also, U.S. Pat. No. 5,015,580(Christou, et al.), issued May 14, 1991 and U.S. Pat. No. 5,322,783.

Another method for physical delivery of DNA to plants is sonication oftarget cells. Zhang, et al., Bio/Technology, 9:996 (1991).Alternatively, liposome and spheroplast fusion have been used tointroduce expression vectors into plants. Deshayes, et al., EMBO J.,4:2731 (1985); Christou, et al., Proc Natl. Acad. Sci. USA, 84:3962(1987). Direct uptake of DNA into protoplasts using CaCl₂)precipitation, polyvinyl alcohol or poly-L-ornithine have also beenreported. Hain, et al., Mol. Gen. Genet., 199:161 (1985) and Draper, etal., Plant Cell Physiol., 23:451 (1982). Electroporation of protoplastsand whole cells and tissues has also been described (D'Halluin, et al.,Plant Cell, 4:1495-1505 (1992); and Spencer, et al., Plant Mol. Biol.,24:51-61 (1994)).

Following transformation of soybean target tissues, expression of theabove-described selectable marker genes allows for preferentialselection of transformed cells, tissues, and/or plants, usingregeneration and selection methods well known in the art.

The foregoing methods for transformation would typically be used forproducing a transgenic variety. The transgenic variety could then becrossed with another (non-transformed or transformed) variety in orderto produce a new transgenic variety. Alternatively, a genetic trait thathas been engineered into a particular soybean line using the foregoingtransformation techniques could be moved into another line usingtraditional backcrossing techniques that are well known in the plantbreeding arts. For example, a backcrossing approach could be used tomove an engineered trait from a public, non-elite variety into an elitevariety, or from a variety containing a foreign gene in its genome intoa variety or varieties that do not contain that gene. As used herein,“crossing” can refer to a simple x by y cross or the process ofbackcrossing depending on the context.

Likewise, by means of one embodiment, agronomic genes can be expressedin transformed plants. More particularly, plants can be geneticallyengineered to express various phenotypes of agronomic interest.Exemplary genes implicated in this regard include, but are not limitedto, those categorized below:

O. A viral-invasive protein or a complex toxin derived therefrom. Forexample, the accumulation of viral coat proteins in transformed plantcells imparts resistance to viral infection and/or disease developmenteffected by the virus from which the coat protein gene is derived, aswell as by related viruses.

Thus, fungal endo-α-1,4-D-polygalacturonases facilitatefungal colonization and plant nutrient release by solubilizing plantcell wall homo-α-1,4-D-galacturonase. See, Lamb, et al., Bio/Technology,10:1436 (1992).

Przibila, et al.,Plant Cell, 3:169 (1991), describe the transformation of Chlamydomonaswith plasmids encoding mutant psbA genes. Nucleotide sequences fornitrilase genes are disclosed in U.S. Pat. No. 4,810,648 to Stalker andDNA molecules containing these genes are available under ATCC AccessionNos. 53435, 67441, and 67442. Cloning and expression of DNA coding for aglutathione S-transferase is described by Hayes, et al., Biochem. J.,285:173 (1992). Protoporphyrinogen oxidase (PPO) is the target of thePPO-inhibitor class of herbicides; a PPO-inhibitor resistant PPO genewas recently identified in Amaranthus tuberculatus (Patzoldt et al.,PNAS, 103(33):12329-2334, 2006). The herbicide methyl viologen inhibitsCO2 assimilation. Foyer et al. (Plant Physiol., 109:1047-1057, 1995)describe a plant overexpressing glutathione reductase (GR) which isresistant to methyl viologen treatment. Bromoxynil resistance byintroducing a chimeric gene containing the bxn gene (Science, 242(4877):419-23, 1988).

D. Acetohydroxy acid synthase, which has been found to make plants thatexpress this enzyme resistant to multiple types of herbicides, has beenintroduced into a variety of plants. See, Hattori, et al., Mol. Gen.Genet., 246:419 (1995). Other genes that confer tolerance to herbicidesinclude a gene encoding a chimeric protein of rat cytochrome P4507A1 andyeast NADPH-cytochrome P450 oxidoreductase (Shiota, et al., PlantPhysiol., 106:17 (1994)); genes for glutathione reductase and superoxidedismutase (Aono, et al., Plant Cell Physiol., 36:1687 (1995)); and genesfor various phosphotransferases (Datta, et al., Plant Mol. Biol., 20:619(1992)).

E. Protoporphyrinogen oxidase (protox) is necessary for the productionof chlorophyll, which is necessary for all plant survival. The protoxenzyme serves as the target for a variety of herbicidal compounds. Theseherbicides also inhibit growth of all the different species of plantspresent, causing their total destruction. The development of plantscontaining altered protox activity which are resistant to theseherbicides are described in U.S. Pat. Nos. 6,288,306, 6,282,837,5,767,373, and 6,084,155.

Any of the above listed herbicide genes (A-E) can be introduced into theclaimed soybean cultivar through a variety of means including but notlimited to transformation and crossing.

3. Genes that Confer or Contribute to a Value-Added Trait, Such as:

A. Modified fatty acid metabolism, for example, by transforming a plantwith an antisense gene of stearyl-ACP desaturase to increase stearicacid content of the plant. See, Knultzon, et al., Proc. Natl. Acad. Sci.USA, 89:2625 (1992).

B. Decreased phytate content: 1) Introduction of a phytase-encoding geneenhances breakdown of phytate, adding more free phosphate to thetransformed plant. For example, see, Van Hartingsveldt, et al., Gene,127:87 (1993), for a disclosure of the nucleotide sequence of anAspergillus niger phytase gene. 2) Up-regulation of a gene that reducesphytate content. In maize, this, for example, could be accomplished bycloning and then re-introducing DNA associated with one or more of thealleles, such as the LPA alleles, identified in maize mutantscharacterized by low levels of phytic acid, such as in Raboy, et al.,Maydica, 35:383 (1990), and/or by altering inositol kinase activity asin, for example, U.S. Pat. Nos. 7,425,442, 7,714,187, 6,197,561,6,2191,224, 6,855,869, 6,391,348, 6,197,561, and 6,291,224; U.S. Publ.Nos. 2003/000901, 2003/0009011, and 2006/272046; and International Pub.Nos. WO 98/45448, and WO 01/04147.

C. Modified carbohydrate composition effected, for example, bytransforming plants with a gene coding for an enzyme that alters thebranching pattern of starch, or a gene altering thioredoxin, such as NTRand/or TRX (See, U.S. Pat. No. 6,531,648, which is incorporated byreference for this purpose), and/or a gamma zein knock out or mutant,such as cs27 or TUSC27 or en27 (See, U.S. Pat. Nos. 6,858,778, 7,741,533and U.S. Publ. No. 2005/0160488, which are incorporated by reference forthis purpose). See, Shiroza, et al., J. Bacteriol., 170:810 (1988)(nucleotide sequence of Streptococcus mutans fructosyltransferase gene);Steinmetz, et al., Mol. Gen. Genet., 200:220 (1985) (nucleotide sequenceof Bacillus subtilis levansucrase gene); Pen, et al., Bio/Technology,10:292 (1992) (production of transgenic plants that express Bacilluslicheniformis α-amylase); Elliot, et al., Plant Molec. Biol., 21:515(1993) (nucleotide sequences of tomato invertase genes); Søgaard, etal., J. Biol. Chem., 268:22480-22484 (1993) (site-directed mutagenesisof barley α-amylase gene); Fisher, et al., Plant Physiol., 102:1045(1993) (maize endosperm starch branching enzyme II); International Pub.No. WO 99/10498 (improved digestibility and/or starch extraction throughmodification of UDP-D-xylose 4-epimerase, Fragile 1 and 2, Ref 1, HCHL,C4H); U.S. Pat. No. 6,232,529 (method of producing high oil seed bymodification of starch levels (AGP)). The fatty acid modification genesmentioned above may also be used to affect starch content and/orcomposition through the interrelationship of the starch and oilpathways.

D. Elevated oleic acid via FAD-2 gene modification and/or decreasedlinolenic acid via FAD-3 gene modification. See, U.S. Pat. Nos.5,952,544, 6,063,947, and 6,323,392. Linolenic acid is one of the fivemost abundant fatty acids in soybean seeds. The low oxidative stabilityof linolenic acid is one reason that soybean oil undergoes partialhydrogenation. When partially hydrogenated, all unsaturated fatty acidsform trans fats. Soybeans are the largest source of edible-oils in theU.S. and 40% of soybean oil production is partially hydrogenated. Theconsumption of trans fats increases the risk of heart disease.Regulations banning trans fats have encouraged the development of lowlinolenic soybeans. Soybeans containing low linolenic acid percentagescreate a more stable oil requiring hydrogenation less often. Thisprovides trans fat free alternatives in products such as cooking oil.

E. Altering conjugated linolenic or linoleic acid content, such as inU.S. Pat. No. 6,593,514. Altering LEC1, AGP, Dek1, Superal1, milps, andvarious Ipa genes, such as Ipa1, Ipa3, hpt, or hggt. See, for example,U.S. Pat. Nos. 7,122,658, 7,342,418, 6,232,529, 7,888,560, 6,423,886,6,197,561, 6,825,397 and 7,157,621; U.S. Publ. No. 2003/0079247;International Publ. No. WO 2003/011015; and Rivera-Madrid, R., et al.,Proc. Natl. Acad. Sci., 92:5620-5624 (1995).

F. Altered antioxidant content or composition, such as alteration oftocopherol or tocotrienols. See, for example, U.S. Pat. Nos. 6,787,683,7,154,029 and International Publ. No. WO 00/68393 (involving themanipulation of antioxidant levels through alteration of a phytl prenyltransferase (ppt)); and U.S. Pat. Nos. 7,154,029 and 7,622,658 (throughalteration of a homogentisate geranyl geranyl transferase (hggt)).

G. Altered essential seed amino acids. See, for example, U.S. Pat. No.6,127,600 (method of increasing accumulation of essential amino acids inseeds); U.S. Pat. No. 6,080,913 (binary methods of increasingaccumulation of essential amino acids in seeds); U.S. Pat. No. 5,990,389and International Publ. No. WO 95/15392 (high lysine); U.S. Pat.

4. Genes that Control Male Sterility:

There are several methods of conferring genetic male sterilityavailable, such as multiple mutant genes at separate locations withinthe genome that confer male sterility, as disclosed in U.S. Pat. Nos.4,654,465 and 4,727,219 to Brar, et al., and chromosomal translocationsas described by Patterson in U.S. Pat. Nos. 3,861,709 and 3,710,511. Inaddition to these methods, Albertsen, et al., U.S. Pat. No. 5,432,068,describes a system of nuclear male sterility which includes: identifyinga gene which is critical to male fertility; silencing this native genewhich is critical to male fertility; removing the native promoter fromthe essential male fertility gene and replacing it with an induciblepromoter; inserting this genetically engineered gene back into theplant; and thus creating a plant that is male sterile because theinducible promoter is not “on” resulting in the male fertility gene notbeing transcribed. Fertility is restored by inducing, or turning “on,”the promoter, which in turn allows the gene that confers male fertilityto be transcribed.

5. Genes that Create a Site for Site Specific DNA Integration:

This includes the introduction of FRT sites that may be used in theFLP/FRT system and/or Lox sites that may be used in the Cre/Loxp system.See, for example, Lyznik, et al., Site-Specific Recombination forGenetic Engineering in Plants, Plant Cell Rep, 21:925-932 (2003) andU.S. Pat.

6. Genes that Affect Abiotic Stress Resistance:

Genes that affect abiotic stress resistance (including but not limitedto flowering, pod and seed development, enhancement of nitrogenutilization efficiency, altered nitrogen responsiveness, droughtresistance or tolerance, cold resistance or tolerance, and saltresistance or tolerance) and increased yield under stress. For example,see U.S. Pat. No. 6,653,535 where water use efficiency is alteredthrough alteration of malate; U.S. Pat. Nos. 5,892,009, 5,965,705,5,929,305, 5,891,859, 6,417,428, 6,664,446, 6,706,866, 6,717,034,6,801,104, 6,946,586, 7,238,860, 7,635,800, 7,135,616, 7,193,129, and7,601,893; and International Publ. Nos.

Nos. 2004/0098764 or 2004/0078852.

Other genes and transcription factors that affect plant growth andagronomic traits, such as yield, flowering, plant growth, and/or plantstructure, can be introduced or introgressed into plants. See forexample, U.S. Pat. Nos. 6,140,085, and 6,265,637 (CO); U.S. Pat. No.6,670,526 (ESD4); U.S. Pat. Nos. 6,573,430 and 7,157,279 (TFL); U.S.Pat. No. 6,713,663 (FT); U.S. Pat.

Genetic Marker Profile Through SSR and First-Generation Progeny

In addition to phenotypic observations, a plant can also be identifiedby its genotype. The genotype of a plant can be characterized through agenetic marker profile which can identify plants of the same variety, ora related variety, or be used to determine or validate a pedigree.Genetic marker profiles can be obtained by techniques such asRestriction Fragment Length Polymorphisms (RFLPs), Randomly AmplifiedPolymorphic DNAs (RAPDs), Arbitrarily Primed Polymerase Chain Reaction(AP-PCR), DNA Amplification Fingerprinting (DAF), Sequence CharacterizedAmplified Regions (SCARs), Amplified Fragment Length Polymorphisms(AFLPs), Simple Sequence Repeats (SSRs) (which are also referred to asMicrosatellites), and Single Nucleotide Polymorphisms (SNPs). Forexample, see, Cregan, et al., “An Integrated Genetic Linkage Map of theSoybean Genome,” Crop Science, 39:1464-1490 (1999) and Berry, et al.,“Assessing Probability of Ancestry Using Simple Sequence RepeatProfiles: Applications to Maize Inbred Lines and Soybean Varieties,”Genetics, 165:331-342 (2003), each of which are incorporated byreference herein in their entirety.

Particular markers used for these purposes are not limited to anyparticular set of markers, but are envisioned to include any type ofmarker and marker profile which provides a means of distinguishingvarieties. One method of comparison is to use only homozygous loci forsoybean cultivar 179565921658.

Primers and PCR protocols for assaying these and other markers aredisclosed in the Soybase (sponsored by the USDA Agricultural ResearchService and Iowa State University). In addition to being used foridentification of soybean variety 179565921658, and plant parts andplant cells of soybean variety 179565921658, the genetic profile may beused to identify a soybean plant produced through the use of soybeancultivar 179565921658 or to verify a pedigree for progeny plantsproduced through the use of soybean cultivar 179565921658. The geneticmarker profile is also useful in breeding and developing backcrossconversions.

One embodiment comprises a soybean plant characterized by molecular andphysiological data obtained from the sample of said variety depositedwith the American Type Culture Collection (ATCC) or with the NationalCollections of Industrial, Food and Marine Bacteria (NCIMB). Furtherprovided by the embodiment(s) is a soybean plant formed by thecombination of the disclosed soybean plant or plant cell with anothersoybean plant or cell and comprising the homozygous alleles of thevariety. “Cell” as used herein includes a plant cell, whether isolated,in tissue culture or incorporated in a plant or plant part.

Means of performing genetic marker profiles using SSR polymorphisms arewell known in the art. SSRs are genetic markers based on polymorphismsin repeated nucleotide sequences, such as microsatellites. A markersystem based on SSRs can be highly informative in linkage analysisrelative to other marker systems in that multiple alleles may be present(“linkage” refers to a phenomenon wherein alleles on the same chromosometend to segregate together more often than expected by chance if theirtransmission was independent). Another advantage of this type of markeris that, through use of flanking primers, detection of SSRs can beachieved, for example, by the polymerase chain reaction (PCR), therebyeliminating the need for labor-intensive Southern hybridization. The PCRdetection is done by use of two oligonucleotide primers flanking thepolymorphic segment of repetitive DNA. Repeated cycles of heatdenaturation of the DNA followed by annealing of the primers to theircomplementary sequences at low temperatures, and extension of theannealed primers with DNA polymerase, comprise the major part of themethodology.

Following amplification, markers can be scored by electrophoresis of theamplification products. Scoring of marker genotype is based on the sizeof the amplified fragment, which may be measured by the number of basepairs of the fragment. While variation in the primer used or inlaboratory procedures can affect the reported fragment size, relativevalues should remain constant regardless of the specific primer orlaboratory used. When comparing varieties, it is preferable if all SSRprofiles are performed in the same lab.

Primers used are publicly available and may be found in the Soybase orCregan supra. See also, U.S. application Ser. No. 09/581,970 (NucleotidePolymorphisms in Soybean); U.S. Pat. No. 6,162,967 (Positional Cloningof Soybean Cyst Nematode Resistance Genes); and U.S. Pat. No. 7,288,386(Soybean Sudden Death Syndrome Resistant Soybeans and Methods ofBreeding and Identifying Resistant Plants), the disclosure of which areincorporated herein by reference.

The SSR profile of soybean plant 179565921658 can be used to identifyplants comprising soybean cultivar 179565921658 as a parent, since suchplants will comprise the same homozygous alleles as soybean cultivar179565921658. Because the soybean variety is essentially homozygous atall relevant loci, most loci should have only one type of allelepresent. In contrast, a genetic marker profile of an F₁ progeny shouldbe the sum of those parents, e.g., if one parent was homozygous forallele x at a particular locus, and the other parent homozygous forallele y at that locus, then the F₁ progeny will be xy (heterozygous) atthat locus. Subsequent generations of progeny produced by selection andbreeding are expected to be of genotype x (homozygous), y (homozygous),or xy (heterozygous) for that locus position. When the F₁ plant isselfed or sibbed for successive filial generations, the locus should beeither x or y for that position.

In addition, plants and plant parts substantially benefiting from theuse of soybean cultivar 179565921658 in their development, such assoybean cultivar 179565921658 comprising a backcross conversion,transgene, or genetic sterility factor, may be identified by having amolecular marker profile with a high percent identity to soybeancultivar 179565921658. Such a percent identity might be 95%, 96%, 97%,98%, 99%, 99.5%, or 99.9% identical to soybean cultivar 179565921658.Percent identity refers to the comparison of the homozygous alleles oftwo soybean varieties. Percent identity or percent similarity isdetermined by comparing a statistically significant number of thehomozygous alleles of two developed varieties. For example, a percentidentity of 90% between soybean variety 1 and soybean variety 2 meansthat the two varieties have the same allele at 90% of their loci.

The SSR profile of soybean cultivar 179565921658 can also be used toidentify essentially derived varieties and other progeny varietiesdeveloped from the use of soybean cultivar 179565921658, as well ascells and other plant parts thereof. Such plants may be developed usingthe markers, for example, identified in U.S. Pat. Nos. 6,162,967, and7,288,386. Progeny plants and plant parts produced using soybeancultivar 179565921658 may be identified by having a molecular markerprofile of at least 25%, 30%, 35%, 40%, 45%, 50%, 55%, 60%, 65%, 70%,75%, 76%, 77%, 78%, 79%, 80%, 81%, 82%, 83%, 84%, 85%, 86%, 87%, 88%,89%, 90%, 91%, 92%, 93%, 94%, 95%, 96%, 97%, 98%, 99%, or 99.5% geneticcontribution from soybean variety, as measured by either percentidentity or percent similarity. Such progeny may be furthercharacterized as being within a pedigree distance of soybean cultivar179565921658, such as within 1, 2, 3, 4, or 5 or less cross-pollinationsto a soybean plant other than soybean cultivar 179565921658 or a plantthat has soybean cultivar 179565921658 as a progenitor. Unique molecularprofiles may be identified with other molecular tools such as SNPs andRFLPs.

While determining the SSR genetic marker profile of the plants describedsupra, several unique SSR profiles may also be identified which did notappear in either parent of such plant. Such unique SSR profiles mayarise during the breeding process from recombination or mutation. Acombination of several unique alleles provides a means of identifying aplant variety, an F₁ progeny produced from such variety, and progenyproduced from such variety.

Tissue Culture

Further reproduction of the variety can occur by tissue culture andregeneration. Tissue culture of various tissues of soybeans andregeneration of plants therefrom is well-known and widely published. Forexample, reference may be had to Komatsuda, T., et al., Crop Sci.,31:333-337 (1991); Stephens, P. A., et al., Theor. Appl. Genet.,82:633-635 (1991); Komatsuda, T., et al., Plant Cell, Tissue and OrganCulture, 28:103-113 (1992); Dhir, S., et al., Plant Cell Reports,11:285-289 (1992); Pandey, P., et al., Japan J. Breed., 42:1-5 (1992);and Shetty, K., et al., Plant Science, 81:245-251 (1992); as well asU.S. Pat. Nos. 5,024,944 and 5,008,200. Thus, another aspect orembodiment is to provide cells which upon growth and differentiationproduce soybean plants having the physiological and morphologicalcharacteristics of soybean cultivar 179565921658.

Regeneration refers to the development of a plant from tissue culture.The term “tissue culture” indicates a composition comprising isolatedcells of the same or a different type or a collection of such cellsorganized into parts of a plant. Exemplary types of tissue cultures areprotoplasts, calli, plant clumps, and plant cells that can generatetissue culture that are intact in plants or parts of plants, such asembryos, pollen, flowers, seeds, pods, petioles, leaves, stems, roots,root tips, anthers, pistils, and the like. Means for preparing andmaintaining plant tissue culture are well known in the art. By way ofexample, a tissue culture comprising organs has been used to produceregenerated plants. U.S. Pat. Nos. 5,959,185, 5,973,234, and 5,977,445describe certain techniques, the disclosures of which are incorporatedherein by reference.

Industrial Uses

The seed of soybean cultivar 179565921658, the plant produced from theseed, the hybrid soybean plant produced from the crossing of the varietywith any other soybean plant, hybrid seed, and various parts of thehybrid soybean plant can be utilized for human food, livestock feed, andas a raw material in industry. The soybean seeds produced by soybeancultivar 179565921658 can be crushed, or a component of the soybeanseeds can be extracted, in order to comprise a commodity plant product,such as protein concentrate, protein isolate, soybean hulls, meal,flour, or oil for a food or feed product.

The soybean is the world's leading source of vegetable oil and proteinmeal. The oil extracted from soybeans is used for cooking oil,margarine, and salad dressings. Soybean oil is composed of saturated,monounsaturated, and polyunsaturated fatty acids. It has a typicalcomposition of 11% palmitic, 4% stearic, 25% oleic, 50% linoleic, and 9%linolenic fatty acid content (“Economic Implications of Modified SoybeanTraits Summary Report,” Iowa Soybean Promotion Board and AmericanSoybean Association Special Report 92S (May 1990)). Changes in fattyacid composition for improved oxidative stability and nutrition areconstantly sought after. Industrial uses of soybean oil, which issubjected to further processing, include ingredients for paints,plastics, fibers, detergents, cosmetics, lubricants, and biodiesel fuel.Soybean oil may be split, inter-esterified, sulfurized, epoxidized,polymerized, ethoxylated, or cleaved. Designing and producing soybeanoil derivatives with improved functionality and improved oliochemistryis a rapidly growing field. The typical mixture of triglycerides isusually split and separated into pure fatty acids, which are thencombined with petroleum-derived alcohols or acids, nitrogen, sulfonates,chlorine, or with fatty alcohols derived from fats and oils to producethe desired type of oil or fat.

Soybean cultivar 179565921658 can be used to produce soybean oil. Toproduce soybean oil, the soybeans harvested from soybean cultivar179565921658 are cracked, adjusted for moisture content, rolled intoflakes and the oil is solvent-extracted from the flakes with commercialhexane. The oil is then refined, blended for different applications, andsometimes hydrogenated. Soybean oils, both liquid and partiallyhydrogenated, are used domestically and exported, sold as “vegetableoil” or are used in a wide variety of processed foods.

Soybeans are also used as a food source for both animals and humans.Soybeans are widely used as a source of protein for poultry, swine, andcattle feed. During processing of whole soybeans, the fibrous hull isremoved and the oil is extracted. The remaining soybean meal is acombination of carbohydrates and approximately 50% protein.

Soybean cultivar 179565921658 can be used to produce meal. After oil isextracted from whole soybeans harvested from soybean cultivar179565921658, the remaining material or “meal” is “toasted” (a misnomerbecause the heat treatment is with moist steam) and ground in a hammermill. Soybean meal is an essential element of the American productionmethod of growing farm animals, such as poultry and swine, on anindustrial scale that began in the 1930s; and more recently theaquaculture of catfish. Ninety-eight percent of the U.S. soybean crop isused for livestock feed. Soybean meal is also used in lower end dogfoods. Soybean meal produced from soybean cultivar 179565921658 can alsobe used to produce soybean protein concentrate and soybean proteinisolate.

In addition to soybean meal, soybean cultivar 179565921658 can be usedto produce soy flour. Soy flour refers to defatted soybeans wherespecial care was taken during desolventizing (not toasted) to minimizedenaturation of the protein and to retain a high Nitrogen SolubilityIndex (NSI) in making the flour. Soy flour is the starting material forproduction of soy concentrate and soy protein isolate. Defatted soyflour is obtained from solvent extracted flakes, and contains less than1% oil. Full-fat soy flour is made from unextracted, dehulled beans, andcontains about 18% to 20% oil. Due to its high oil content, aspecialized Alpine Fine Impact Mill must be used for grinding ratherthan the more common hammer mill. Low-fat soy flour is made by addingback some oil to defatted soy flour. The lipid content varies accordingto specifications, usually between 4.5% and 9%. High-fat soy flour canalso be produced by adding back soybean oil to defatted flour at thelevel of 15%. Lecithinated soy flour is made by adding soybean lecithinto defatted, low-fat or high-fat soy flours to increase theirdispersibility and impart emulsifying properties. The lecithin contentvaries up to 15%.

For human consumption, soybean cultivar 179565921658 can be used toproduce edible protein ingredients which offer a healthier, lessexpensive replacement for animal protein in meats, as well as indairy-type products. The soybeans produced by soybean cultivar179565921658 can be processed to produce a texture and appearancesimilar to many other foods. For example, soybeans are the primaryingredient in many dairy product substitutes (e.g., soy milk, margarine,soy ice cream, soy yogurt, soy cheese, and soy cream cheese) and meatsubstitutes (e.g., veggie burgers). These substitutes are readilyavailable in most supermarkets. Although soy milk does not naturallycontain significant amounts of digestible calcium (the high calciumcontent of soybeans is bound to the insoluble constituents and remainsin the soy pulp), many manufacturers of soy milk sell calcium-enrichedproducts as well. Soy is also used in tempe, where the beans (sometimesmixed with grain) are fermented into a solid cake.

Additionally, soybean cultivar 179565921658 can be used to producevarious types of “fillers” in meat and poultry products. Food service,retail, and institutional (primarily school lunch and correctional)facilities regularly use such “extended” products, that is, productswhich contain soy fillers. Extension may result in diminished flavor,but fat and cholesterol are reduced by adding soy fillers to certainproducts. Vitamin and mineral fortification can be used to make soyproducts nutritionally equivalent to animal protein; the protein qualityis already roughly equivalent.
